  1. 1. INTERSEKTIONALITET I EU:S JÄMSTÄLLDHETSSTRATEGIER En innehållsanalys av EU:s jämställdhetsstrategier mellan 2010–2025

    Kandidat-uppsats, Göteborgs universitet/Statsvetenskapliga institutionen

    Författare :Michaela Karlsson; [2024-02-05]
    Nyckelord :EU; gender equality; gender equality strategies; intersectionality; qualitative literature analysis EU; jämställdhet; jämställdhetsstrategi; intersektionalitet; kvalitativ innehållsanalys;

    Sammanfattning : The European Union (EU) has since the Treaty of Rome 1957 pursued the goal of gender equality and one effort is through their gender equality strategies. In recent years EU also has had an increased emphasis on intersectionality. LÄS MER

  3. 2. Life cycle assessment of metal laser powder bed fusion : A deep dive into the significance of system boundary expansion and improvement potential

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Christian Rotter; Erik Fagerberg; [2023]
    Nyckelord :additive manufacturing; life cycle assessment; powder bed fusion; system boundaries; metal laser powder bed fusion; environmental impact; global warming potential;

    Sammanfattning : Metal additive manufacturing (MAM) is a manufacturing technology experiencing a rapid expansion rate. Metal laser powder bed fusion (ML-PBF) is among the most popular techniques in this field. The environmental implications of it are often discussed in literature and compared to conventional manufacturing. LÄS MER

  4. 3. Kontinuerlig rötning med hydrokol för högre biogasutbyte

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Annette Kariis; [2023]
    Nyckelord :Biogas; Continuous anaerobic digestion; Hydrochar; Hydrothermal Carbonisation; Life-cycle costing; Biogas; kontinuerlig anaerob rötning; Hydrokol; Hydrotermisk karbonisering; Livscykelkostnad;

    Sammanfattning : Befolkningsökningen och därmed efterfrågan på energikällor som tillhandahålls från fossila bränslen leder till allvarliga miljöproblem på grund av utsläpp av växthusgaser. En annan utmaning är att effektivt hantera organisk avfall som till exempel matavfall som genereras världen över. LÄS MER

  5. 4. Additively Manufactured Rare Earth Free Permanent Magnets

    Master-uppsats, Uppsala universitet/Tillämpad materialvetenskap; Uppsala universitet/Oorganisk kemi

    Författare :Himesha Abenayake; [2023]
    Nyckelord :additive manufacturing; MnAl; MnAl C ; rare earth free permanent magnets; selective laser melting; SLM; MnAl-based permanent magnets;

    Sammanfattning : It’s well known that MnAl(C) material consists of a metastable phase (τ) with promising ferromagnetic properties, produced either by controlled cooling from the high-temperature hexagonal ε-phase or rapid cooling that freezes the ε-phase followed by low-temperature annealing. Due to the high cooling rates involved, additive manufacturing (AM) especially selective laser melting (SLM), has been identified as a possible method to retain the high-temperature ε-phase, hence containing a potential capacity to produce permanent magnets upon low-temperature annealing.

  7. 5. Modified cellulose synthesized by different deep eutectic solvents as an additive in paper making process

    Master-uppsats, Karlstads universitet

    Författare :Shiniar Said Saleh; [2023]
    Nyckelord :green chemistry; dry strength additives; deep eutectic solvents; sodium periodate oxidation; charge density; dewatering; mechanical strength.;

    Sammanfattning : The environmental concerns that come with the currently used traditional papermaking process where petroleum-based additives are used, has tempted researchers to study “green” additives by introducing environmentally friendly modifications of cellulose as an additive in the papermaking process. This thesis will spin further on that by producing additives with different charge densities and focus on to incorporate an etherification reaction into potentially greens systems based on non-toxic and readily biodegradable deep eutectic solvent (DES).
